thermonuclear processes

Thermonuclear processes involve nuclear fusion, where light atomic nuclei, like hydrogen isotopes, combine at extremely high temperatures and pressures to form a heavier nucleus, releasing a tremendous amount of energy. This is the same process that powers the Sun and other stars, producing their heat and light. In stars, gravity creates the necessary conditions for fusion to occur naturally. On Earth, scientists attempt to replicate these conditions in reactors to generate clean energy. Fusion is different from nuclear fission, which splits heavy atoms apart; fusion promises a safer, abundant energy source with less radioactive waste.
